A useful variant of the Davis--Kahan theorem for statisticians

TL;DR: In this paper, the authors present a variant of the Davis-Kahan theorem that relies only on a population eigenvalue separation condition, making it more natural and convenient for direct application in statistical contexts, and provide an improvement in many cases to the usual bound.
Journal Article

Ultrahigh Dimensional Feature Selection: Beyond The Linear Model

TL;DR: This paper extends ISIS, without explicit definition of residuals, to a general pseudo-likelihood framework, which includes generalized linear models as a special case and improves ISIS by allowing feature deletion in the iterative process.
Journal ArticleDOI

Choice of neighbor order in nearest-neighbor classification

TL;DR: In this paper, the authors consider two models, Poisson and Binomial, for the training samples, and show that the risk of misclassification is asymptotically equivalent to first order.
Journal ArticleDOI

Variable selection with error control: another look at stability selection

TL;DR: In this article, a variant of stability selection, called complementary pairs stability selection (CPSS), is introduced, and bounds are derived on the expected number of variables included by CPSS that have low selection probability under the original procedure.
